Inlet Valve Lubrication Metering Pump
An inlet valve lubrication metering pump is provided in order to lubricate the inlet valves during operation. The valve is adjusted at the factory and the valve will not normally require adjustment unless the pump is replaced.

Oil Leakage On Outside Of Engine
Check for leakage at the seals at each end of the crankshaft. Look for leakage at the oil pan gasket and all lubrication system connections. Look for any oil that may be leaking from the crankcase breather. This can be caused by combustion gas leakage around the pistons. A dirty crankcase breather will cause high pressure in the crankcase. A dirty crankcase breather will cause the gaskets and the seals to leak. Oil Leakage Into Combustion Area Of Cylinders
Oil leakage into the combustion area of the cylinders can be the cause of blue smoke. There are four possible ways for oil leakage into the combustion area of the cylinders:
Oil leakage between worn valve guides and valve stems
Worn or damaged pistons, piston rings, or dirty oil return holes in the piston
Incorrect installation of the compression ring and/or the intermediate ring
Oil leakage past the seal rings in the impeller end of the turbocharger shaftToo much oil consumption can also be the result if oil with the wrong viscosity is used. Oil with a thin viscosity can be caused by increased engine temperature. Measuring Engine Oil Pressure
The engine oil pressure and the oil filter restriction can be measured with the electronic service tool.
Work carefully around an engine that is running. Engine parts that are hot, or parts that are moving, can cause personal injury.
Oil pressure to the camshaft and main bearings should be checked on the side of the cylinder block at the oil gallery plug. With the engine at operating temperature, the minimum oil pressure at full load rpm should be approximately 280 kPa (40 psi). Minimum oil pressure at low idle rpm should be approximately 140 kPa (20 psi) .Oil Pressure Is Low
Crankcase Oil Level
Check the level of the oil in the crankcase. Add oil if oil is needed. It is possible for the oil level to be too far below the oil pump supply tube. This will cause the oil pump not to have the ability to supply enough lubrication to the engine components.This engine also uses a scavenge oil pump to move trapped oil from the rear of the engine back to the main sump at the front. Be sure that this oil pump operates correctly in order to maintain a sufficient oil level for the main oil pump supply tube.The Oil Pump Does Not Work Correctly
The inlet screen of the supply tube for the oil pump can have a restriction. This restriction will cause cavitation
